Application filed September 14, 1907. Serial No. 892,886.

canon, a citizen of the United States, residing at Preston, in the county of Lancaster, England, have invented a certain new and useful Improvements in Controllers, of which the following is a full, clear, and exact description, reference being had to the accompanying drawings.

' The object of this invention is to provide a simple and compact controller of a type suitable for" railway service and the like.

The invention comprises the general arrangement of parts and details thereof, including a number of novel features which contribute to the efficiency of the controller.

Among these may be mentioned the arran e- V ment and mechanism for cutting out a efective motor; the contact, fingers so arby the main springs; the blow out; the special indicating arrangement operated by the controller handle; the construction and fastening arrangement of that handle, and the arrangement of the contact fingers in two sets on two connection boards. These features will be more fully hereinafter described and the essential characteristics set out in the claims. 1

In the drawings, Figure 1 is a front elevation' of the control'lem'Fig. 2 is a sectional side elevation thereof looking from the left; Figs. 3, 4 and 5 are horizontal sections, substantially onthe correspondingly numbered lines of Fig. 1'; Fig. 6 is a plan of the top plateof the controller; Fig. 7 is a vertical section through the handle; Fig. 8 is a cross section of the same .on the line 8-8 of Fig. 7 Fig. '9 is a side elevation of one such finger; Fig-s11, 12 and 13 are three diagrams indicating the different positions of the reversin switch; Fig: 14 is a complete wiring diagram of a car equipped with this controller.

Referring first to Figs. 1 to 5 inclusive, 20 and 21 represent two connection boards which extend vertically at the front and 1 back oft-he controller, the board 21 being troller case and the board 20 being fastened by screws to brackets 23 and 33 secured to the back plate. Secured to each connection boardare two sets of contact fingers, one set 24 cooperating with the governing cylinthe reversing cylinder. cylinder comprises a shaft 26 having an 1nranged that their adjusting screws are locked of the contact fingers; Fig. 10 is a plan of secured to the back plate 22 of the con-' der, and the other set cooperating with The governlng sulating sleeve 27, around which is a segmental wooden cylinder 28, to which are secured the contact arms 29 having removable contact segments. These segments are arranged intwo sets some 31, as shown -more particularly in the diagram, Fig. 14.

The contactfingers 24, carried by both the front and rear connection boards, cooperate -with these segments. These contact fingers (which will be hereinafter more specifically described) are mounted on brackets 32 which are secured on the sides of the connection.

boards'and extend around their edges, as shown in Fig. 4, the contact fingers thus springing in the-instance shown from the left hand corner of the boards.

The reversing switch comprises the shaft 35 which is surrounded by an insulating sleeve, the sleeve being surrounded by the wooden cylinder 36. On the surface of this cylinder are contact plates 37 arranged in two sets to coiiperate with the two sets of contact fingers 25. These latter fingersare carried by brackets 39, which, as shown, are secured to the right hand corners of the connection boards.

The blow out designated 40 stands vertically with its axis in the plane passing upper and lower ends of the blow out are horizontal terminal plat-es 11 and 12. These plates are adapted to be engaged by the contact fingers 10 carried by the brackets 23 and 33, to make a good electrical connection. the blow out being held in place by pins 9 which are engaged by pivoted spring-pressed fingers 8 carried by these brackets. \Vhcn these fingers are turned away from the blowout, as shown in dotted lines in Fig. 1. the same may be removed, While when the rearmost fingers release their pins 9, the blow out becomes hinged on the front pins 9 and may be swung forward on its pins without direction cutting out the other set.

breaking the electrical connection through theblow out.

The described arrangement of governing cylinder, reversing cylinder, blow out and swinging the blow out aside on its hinges,

the governing fingers'maybe easily reached. The whole interior of the casing may be conveniently removed and the connection boards and the parts they carry easily taken ofi for repairs.

The controller shown is adapted to control four motors arranged in two sets, as shown in the diagram (Fig. 14) where motors 1 and 2 constitute one set and Nos. 3 and 4 the other set. 'In cutting out a disabled motor, it is preferable to cut out the completepair, thus enabling the controller .to operate the remaining pair in series and -p'ar'allel. In order to conveniently cut out either pair of motors as desired, the reversing switch has been arranged in this invention so that its barrel may be longitudinally shifted, the shifting in one direction cutting out one set ofmotors, and that in the other The mechanism by which this is accomplished will now be described.

Mounted on the barrel-of the reversing switch, near the middle of its length, is a grooved ring 45 which operates loosely within a bracket 46, which is secured to the edge of the two connection boards. Pivoted to this bracket isa locking finger 47 which is forced toward the reversing switch by a spring 48; This finger is provided with a tooth 50 adapted to project through an opening in the bracket, and normally occupying the groove in the ring 45. In this position the reversingswitch has all of its contact plates in position to aline with the two sets of contact fingers 25. These plates, however, are farther apart than the width of the contact fingers, and the ring 45 is. so proportioned that if the locking'finger is with- 'drawn and the barrel elevated or depressed until the finger returns to position above or below the ring, the plates will be shifted so that certain of the contact fingers will be out of the alinement with the contact plates.

This cuts out the corresponding motors.

fingers and segments'when the barrel has been shifted downward. In this case the lower sets of segments are rendered inetiec-, tive, cutting out motors Nos. 3 and 4. When either pair of motors is cut out the other pair is controlled in series and parallel as usual. In order to allow the up and down movement to the reversing switch barrel, the shaft '35 of this barrel is slidably mounted in the base 48 of the controller and slidably in a socket in the operating stem 49 which carries the handle 53. Rigid on this stem is the indicator wheel 50". This wheel carries a pin 51 slidable in a hole .in the head 52 on the reversing switch. This pin furnishes the means for driving the revers ing switch from the stem 49 and allows shifting as explained.

YFig. 3 shows a usual form of indicating wheels and interlocking-mechanism for the two barrels. The indicator wheel 50, as,

- stated, is on the stem of the reversing switch tween the two indicating wheels :are the arms 60 and 61, carrying rollers cooperating 'with' the'wheels, these arms being pressed,

apart by a spring 62 and being so constructed that there is only room for one of them at a time to be out of engagement with a notch in its indicator wheel.

To give a decided stop for each indicator notch, the following mechanism is provided. On the top plate '65 of the controller are mounted the ra-ised'substantially radial lugs 66 corresponding to the indicator notches, and mounted vertically in the handle 67 is a dog or pawls. 68 which is adapted to engage these lugs. Engaging with the upper portion of this dog is a lever 69, which is pressed upward by spring 7 0 and has its extreme end occupying a groove 71 in the stem 72 of lmob 73. The spring 70 has sufficient force-to velevate the knob and dog. The'natural downward'pressure of the operators hand, however-is suflicient to depress the spring and lower the dog so that it ext-ends 1n theway of the lu in advance thereof, this lowered position oi the dog being indicated by dotted lines in Fig. 7

The dog is mounted loosely in a guideway 75 formed in a downward extension of the main portion of the handle. This guideway 7 5 flares downwardly as shown in Fig. 8 to allow the dog some movement in the general direction. in which the'handle travels. A spring 78 on the back side of the dog normally holds it'in its forward position, as shown'in Fig. 8. WVhen, however, the dog engages a lug 66, itswings rearward into the position shown by dotted lines in Fig. 8. Now, as the operator slightly releases the pressure of his hand on knob 73, the spring 70 lifts the knob and dog. The dog thus goes'back into normal position ready to engage the next lug when the handle moves up to it.

In order to secure a good fastening between the handle 67 and the spindleST, a hole 80 is drilled slightly diagonally through the handle and spindle, tion, and in this hole within the handle is sweated a pin 81. This pin, when the bandle in place, finds its bearing in the groove in the spindle and wedges against the spindle, making a perfectly firm hold. At the same time the handle may be removed from the spindle whenever desired. The spindle is provided with an umbrella 83 to water from entering the interior of the controller.

The contact fin er which I employ for the ler is shown in Figs. 4, 9

the shank 91, the bracket 92, to which the Shank is pivoted at 87, the copper shunt 93 connected-to the finger and bracket. This bracket 92-is provided with a slotted opening 94 and is secured by a screw 95 (Fig. 4

to the bracket 32 carried by the connection The slotting of the opening 94 allows the'removal of the finger as a whole whenever desired. 96 indicates astop screw which-screws through the bracket 92 and has its inner end in position to be engaged by an arm 97 of the finger which extends frToliln e main spring 98 for the finger is riveted to its shank 91 and lies against the hexagon head of the crew, 96. By this means the spring itself forms the lock for the screw, obviating the necessity for a special locknut, and allowing the adjustment to be made quickly'and" with more ease. An outward stop for the finger is provided These latter fingers have no circuits and are v provlded to serve as wipers for the arcs to spring from.
